Y PUNCH.

Patented July 25, 1922.

Application filed January 5, 1920. Serial No. 349,372.

To all whom it may concern:

Be it known that 1, JOHN Q. SHERMAN, a citizen of the United States, and a resident of the city of Dayton, county of Montgomery, and State of Ohio, have invented certain new and useful Improvements in Roof holes in any desired material, and more particularly for punching out a series of holes in strips of paper. It is also employed as an attachment in connection with rotary presses for printing up into forms a continuous web or strip of paper, such as are used in autographic register or multigraph work.

It will be understood that the mechanism shown apart from the punch itselfand the operative parts thereof is selected for pur-- poses of illustration. It should be noted further as to the general type of mechanism that the punches while rotary do not operate like a revolving head to punch out successive crosswise rows of holes from a strip of paper or whatever medium is selected, but punch out the desired series of holes lengthwise as well as crosswise of the strip. I have found that this principle will result in a more certain uniformity of spacing of the holes, and permit of a more accurate and positive operation than revolving head rotary punches which operate to punch but one crosswise set of holes at each step by step movement of the paper, or in other words have a truly continuous mode of operation.

My advantages in structure and operation, and the objects above noted I accomplish by that certain construction and arrangement of parts to be more specifically pointed out and claimed.

In the drawings,

Figure 1 is a side elevation of the complete mechanism.

Figure 2 is a section taken on the line 22, of Figure 1. a

Figure 3 is a side elevation of the punch bars on a larger scale than Figure 1.

Figure 4 is a detail vertical section through the punch bar.

The machine shown has a frame 1, and a power driven gear 2. A. storage roll 3 for paper 4 is shown, said paper being fed by means of a driven roll 5 and contacting with a friction roll 6. 7'

For removal of the paper from the machine no mechanism is shown but it will be.

understood in the matter that follows that the paper is controlled by the driven roll 5 so that the proper amount goes to the punches. Some sort of control for'the paper such as this will be required except where the punches are used in a printing press, or some other material than paper is employed. 1

The punch bars are driven from the gear 2 by means of a. pinion 7. This pinion meshes with a gear 8, which in turn meshes with a pinion 9 on the shaft 10 of the feeding roll 5. The amount of paper issued to the punches is thus controlled absolutely by the relative sizes of the gears and roll 5, the friction roll 6 being adapted to normally press tightly against thesaid feed roll 5.

- Mounted at the receiving end of the punch bar mechanism at each'side thereof, are the upper and lower stub shafts 11 and 12, suitably held in the frame and at the issuing end of the'punch mechanism are the upper and lower shafts 13 and 14. These shafts support for the upper shafts. the cranks 15, 15 and for the lower shafts the cranks 16, 16' these cranks being mounted .on the shafts on the inside of the frame 1. Each pair of cranks 15, 16 support cross rods 17 and 18, of which 17 are the upper rods at the front and back of the mechanism and 18 are the lower rods. Journaled on the said rods are the desired number of punch bars, of which the male bars are indicated at 19 and the female at 20. The bars are held in place by collars 21, secured in position by set screws 22. The desired number of bars can be mounted crosswise of-the mechanism and permanently and, accurately located by meansof the collars 21.

Although but one set of punch bars is shown, it will be understood that normally a device of this character will employ several sets and between the bars of a set are located standards 23 which carry at their upper ends'paper supporting plates 24.

On the outside of the frame the pair of stub shafts 11 have rigidly secured to them cranks 25, 25 and the shafts 12 have rigidly secured cranks 26, 26. The shaft 12 at the one side of the machine has mounted fast thereon a pinion 7 which, it will be remembered, is driven by the gear 2.

Cranks 25 and 26 have links 27 and 28 respectively, which at each side of the ma chineare connected to cylinders 29-and 30.

The cylinders 29 and 30 slide in bosses 31,

32 mounted on the frame of the machine.

By this mechanism the shafts l1 and 12 are driven. The gear 2 and pinion 7 im- 10 part motion to the shaft 12 and its outer crank 26. Through the medium of the link 28 for its crank 26 and the cylinder 29 and link 27, motion is communicated to the shaft 11. On the interior of the machine the crossbar 17 for the two shafts 11 and the cross-rod 18 for the two shafts 12 will transmit the. motion from the left to the right hand side of the machine, although it may be preferred to provide a duplication of the \gear 2, and pinion 7 on the right hand side of the machine.

The two crank link cylinder combinations at the right and'left hand side of the machine are set at different angles in order to avoid a dead center and insure smooth operation.

The shafts 13 and 14 at the forward or delivery end of the machine serve merely as hangers 'for the cranks 15 and 16. The

punch bars being journaled on the crossrods 17, 17 and 18, 18, will move through a circular path always remaining in a horizontal plane.

T he punch mechanism.

The punch bars 19 which carry the unches also carry a stripping mechanism.

he bar 20 is merely apertured to receive the punches.

The preferred construction of the bar 20 comprises a lengthwise body 20 re-enforced by a nb 33 at each side of which are apertures 34, the apertures being, in this particular instance, formed in pairs lengthwise of the bar. The bar is surfaced of suitable metal which has accurate-l formed apertures 36, 36, aligned withthe apertures 34 and carefully formed to receive the punches of the upper bar.

The upper bar is formed of a body 19 reenforced by a rib 87. The under side of this body has secured to it the plate 38. The plate 38 carries the punches 39 which are arranged in pairs lengthwise of the structure. The plate 38 is also s'ocketed at 40 to form housings for springs 41, these sockets and springs being preferably four or five in number throughout the length of the bar,

although, of course, the exact number is v unessential.

The body 19 of the bar is perforated for the passage of pins 41, 41, which extend through the sockets 40, above noted, and

have mounted on their ends the stripper plate 42 which extends the whole length of of longitudinally arranged matching holes by a plate 35- the bar mechanism. The springs 41" bear'on the stripper plate and the plate is accurately apertured to ride over the punches 39, 39.

It is so constructed that when a sheet of material is placed between two bars and the mechanism set in motion, the two bars will be brought up against or adjacent each other at the upper and lower limits of their rotation respectively with the punches perforating the paper and entering the apertures in the lower ar throughout the entire length of the bars. v

The stripper plate comes into contact with the paper and lower bar simultaneously with the punches, or slightly in advance thereof, if desired. The one continued motion of the mechanism separates the two bars and the punches ride out of the lower bar and the stripper will lift the paper from the pin. The exact contactual relation of the two bars is not essential, as the only necessary operation is that of the punches and holes; the stripper being carried on the bars or separated from them.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a rotary punch, the combination with operating mechanism, of a single pair of punch bar elements extending lengthwise of a web of paper to be punched, the one bar carrying an extended number of longitudinally arranged punches, and the other bar provided with a similar number for the punches, and means actuated by the operating mechanism for moving said bars toward and away from each other through a rotary path while maintaining them in parallel with relation to each other and means for controlling the amount of material fed between said bars, whereby the holes shall be punched in spaced series for the several punching operations.'
